UNITED STATES PATENT OEEICE JOSEPH W. STRANGE, BANGOR, MAINE.

IMPROVEMENT IN cHuRNs.

Specification forming part of Letters Patent No. l 56.444, dated November 3,1874; application filed i March 6, 1874.

To all whom t may concern: l

Be it known that I, J osEPII W. STRANGE, of Bangor, in the county of Penobscot and State of Maine, have invented new and useful Improvements in Train of Gearing for Ohurns and other purposes, of which the following isY a specification:

This invention is primarily intended to be applied to the class or kind of churns known as rotary; and the invention consists in a train ofpvarying-sized gear-wheels connected with the central shaft, and driven through the medium of a crank, which is interchange- I dash may be driven direct by the crank.

Figure llis a horizontal section of a churn and the attachment, taken through the axis of the gear-wheels and the pivot of the dash.

.Fig 2 is a side elevation of a churn and attachment, a part of the teeth on the gear- Fig. 3 is an enlarged detached section, showing the device attaching the crank to the studs.

A A are the ends7 and B B the sides, ofthe hull. O O are a pair of the arms, and D D two of the oats of the dash. The dash at one end revolves upon the pivot a, while the other end is supported and revolved by the stud b, as will be more fully described. c is a plate, detachably secured to end A. The hollow sleeves d e f are formed upon or secured to plate c, at suitable distances from each other. The studs or short arms g h c' are tted and y revolve, respectively, in the sleeves, as shown in Fig. l, and the gear-wheels'j k l are, respectively, formed or secured upon the studs, as shown. The studs are secured from end rotation of the studs, and ready means for their removal, whenever desirable. The studs g 'i need only pass through plate c; but stud h passes through and actuates-the dash-shaft or other shaft, as before stated.

Gear k is but about half the diameter of gear l, and but little more than one-third of that of gear j. V

Crank n is applied with equal facility to either of the studs7 and is secured thereto by the spring-catch o, secured in the angle of the socket by pin 1o, and iitting into the recess s in the corner of the rightangled ends of the studs, and it is released by actuating the projecting end of the spring.

It will be apparent that, when the crank is applied to stud g, the rotations of the dash relatively to the crank will be in the ratio of gears j k, and that, while the dash is thus driven, gear Z serves only the part of an idler; but when the` gathering butter, or other retarding iniiuence, commences to resist the revolution, the crank can be instantly changed to stud o', when j becomes the idler, and vl transmits the power. Then, when the resistance renders it necessary, the crank is transl ferred to stud h, and the dash is driven direct, leaving both j and Z to play the part of idlers. 5

I do not claim, broadly, in combination with a rotary dash, a train of multiplying-gears,
